Transarterial radioembolization with yttrium-90 microspheres is an established therapy for hepatocellular carcinoma. Post-procedural imaging is important for the assessment of both treatment response and procedural complications. A variety of challenging treatment-specific imaging phenomena complicate imaging assessment, such as changes in tumoral size, tumoral and peritumoral enhancement, and extrahepatic complications. A review of the procedural steps, emerging variations, and timelines for post-treatment tumoral and extra-tumoral imaging changes are presented, which may aid the reporting radiologist in the interpretation of post-procedural imaging. Furthermore, a description of post-procedural complications and their significance is provided.
经动脉放射性栓塞术用钇-90 微球是治疗肝细胞癌的一种成熟疗法。术后影像学检查对于评估治疗反应和手术并发症都很重要。各种具有挑战性的特定于治疗的影像学现象使影像学评估变得复杂，例如肿瘤大小、肿瘤和肿瘤周围增强以及肝外并发症的变化。本文回顾了治疗步骤、新兴的变化以及治疗后肿瘤和肿瘤外影像学变化的时间线，这可能有助于报告放射科医生解读术后影像学。此外，还描述了术后并发症及其意义。
